I dried the roses in my December birthday bouquet from my son, Neil. The pink ones have kept their colour.
For rainbow2017 I'm following the six-band rainbow: red, orange, yellow, green, blue, purple, and adding pink as I find indigo both elusive and boring.
That's the word I was looking for!
Sam, no but I guess I could spray it with something?!
I'll give it a spray of lavender!
